A good disk, 6 TB is enough for me and everything is fine with games. I use it a little and have nothing to say but so far so good. Everything is fine, the disk works great. It vibrates, you can get used to it as it’s not that strong  Renal Arifullin: use Toshiba HDWT140UZSVA few months |
It’s just the second month of its operation, it records all this time without stopping, both on weekdays and on weekends, it’s ideal for storing because it records video from a bunch of sources at the same time, you can immediately view the recorded video - no lags, missing files or other problems. The head rotates quietly, the heating level is not high even without rest. Response times, read and write speeds are mixed, random and sequential are fine. It is specifically designed for working with video, because there are nuances for other tasks, well, with tasks where only linear access to data is also suitable. No, the disc is good.

Basic Level
The Toshiba S300 HDWT840UZSVA hard drive features a well-designed internal architecture aimed at use in surveillance systems. The device belongs to the affordable segment due to the brand’s pricing strategy and the use of basic SMR recording technology, which is optimal for data reading tasks. At the same time, the combination of proprietary Dynamic Cache technology and a 256 MB buffer ensures a decent data transfer speed. The drive can reliably handle video streams from 64 cameras simultaneously and is suitable for server solutions of various formats — DVR, NVR, and hybrid systems. The 4 TB capacity is optimal for long-term archive storage without frequent overwriting, both in home and corporate security systems.
Overall Reliability
The fault tolerance level and build quality are at a good level for its class. The manufacturer claims enhanced durability of the casing, as well as the use of rotational vibration sensors and the Toshiba Stable Platter platform, which reduce the impact of vibrations and ensure stable operation in multi-drive NAS systems. The drive is designed for approximately one million hours of continuous operation in 24/7 mode and operates reliably at temperatures up to +70 °C thanks to automatic intelligent control of power consumption and rotation speed.
